Just let go...

Ok, I am having a big problem. To some it is going to sound stupid, but I am feeling really guilty for the way everything is going at work. It seems like since I have gone out that anything that can pop up has. I really don't understand why I can't be one of those people to just walk away from it and take the time I need. I feel like I have to help as much as I can, and I guess part of the problem is that I know the staff is already so over worked and has so much on their plates, that I feel bad that they have to pick up my slack. I wanted things to go smoother when I left and I know that I can not help that I delivered early, but I feel that I need to make up for what has happened. How do you let go? Some people can, and I think that if I had left on a more planned out note, then it would be fine. I don't like it when things are beyond my control and I can't fix things. That is why I guess I am trying to "fix" the fact of how I left, but that is a job that is going to be impossible. By no means do I think that they can't make it with out me, I know they can, I just can't help but feeling like I have dumped on my team. Everyone keeps telling me that I shouldn't feel bad, but I do, I lay in bed thinking,"oh they need to pull this," or I am in the shower, "Oh, I forgot to tell them how to do this." It is on my mind almost all the time. How do you just clear it? I had a card reader tell me one time that it is like I am married to my job. If I was to cheat on my husband it would be with my job. How sad is that? I just feel like there is always something else I need to do. Maybe one day I will figure it out, but right now it is killing me.
